BACKGROUND OF THE INVENTION Technical Field

This invention relates generally to an infusion bag and more particularly to a multi-mix infusion bag.

State of the Art

The use of infusion bags has been critical in the medical industry. These bags have been the means of delivering many types of fluids to patients, for example for various types of intravenous therapies, such as, but not limited to, correcting electrolyte imbalances, delivering medications, transfusing blood, or replacing fluid to correct conditions such as dehydration.

A conventional infusion bag typically contains only one solution. Further, it is not able to prevent issues of improper mixing by an administrator (such as a medical professional or pharmacy employee) due to human error. Any mixture of components must also be prepared on site, which results in a risk of contamination. This risk is much greater due to the various sites (location not being sterile) that the mixture will be prepared in. A conventional infusion bag also does not assure the quality of its contents, does not minimalize variance of the mixed contents (the mixer is at times inconsistent), and administration is more cumbersome because the mixture must be prepared before administering a solution to the patient. These drawbacks make it difficult to provide a mixture of components in an infusion bag for delivery to a patient.

Accordingly, there is a need for an improved infusion bag to address these drawbacks.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

As discussed above, embodiments of the present invention relate to a multi-mix infusion bag comprising multiple agents stored separately and mixed within the infusion bag prior to dispensing. Embodiments of the invention can be sold pre-filled and ready to use; reduces risk of human error; reduces risk of contamination; increases ease of administration; simplifies the process of administrating infusions intravenously; protects content from oxidation; assures accurate administration; permits little to no variance between the mixtures; increases the contents shelf life; and prevents contents from reacting adversely and prematurely.

Referring to the drawings, FIGS. 1 and 3 depicts a multi-mix infusion bag 10 in a stored condition, according to embodiments. The multi-mix infusion bag 10 comprises an upper portion 11 and a lower portion 13. The lower portion 13 comprises a main chamber 12. The upper portion 11 may comprise multiple compartments. For example, as shown, and without limitation, the upper portion 11 may include a first chamber 40, a second chamber 41, a third chamber 42, a fourth chamber 43, a fifth chamber 44 and a sixth chamber 45. The multi-mix infusion bag 10 comprises chamber separating members 17, to separate fluid agents 50, 51, 52, 53, 54 and 55, wherein first fluid agent 50 is held within first chamber 40, second fluid agent 51 is held within second chamber 41, third fluid agent 52 is held within third chamber 42, fourth fluid agent 53 is held within fourth chamber 43, fifth fluid agent 54 is held within fifth chamber 44, and sixth fluid agent 55 is held within sixth chamber 45. Additionally, the multi-mix infusion bag 10 may comprise a separating wall 18. The separating wall 18 separates the upper portion 11 from the lower portion 13 of the bag 10. The separating wall 18 serves to maintain the fluid agents 50-55 from entering lower chamber 12. The maintaining of the fluid agents 50-55 separate keeps the agents from reacting with one another until the appropriate time for the agents to be mixed. This increases shelf life. The first through sixth chambers 40-45 may each hold a predetermined amount of fluid. The separation of the fluid agents 50-55 constitutes the stored condition.

Further, within each upper chamber 40-45, the multi-mix infusion bag 10 may comprise interior dispensing devices. For example, a first dispensing device 20 corresponds to the first chamber 40, a second dispensing device 21 corresponds to the second chamber 41, a third dispensing device 42 corresponds to the third chamber 22, a fourth dispensing device 23 corresponds to the fourth chamber 43, a fifth dispensing device 24 corresponds to the fifth chamber 44, and a sixth dispensing device 25 corresponds to the sixth chamber 45. Each dispensing device 20-25 may be a plunger and include a perforating device. The first dispensing device 20 may include a first perforating device 30, the second dispensing device 21 may include a second perforating device 31, the third dispensing device 22 may include a third perforating device 32, the fourth dispensing device 23 may include a fourth perforating device 33, the fifth dispensing device 24 may include a fifth perforating device 34, and the sixth dispensing device may include a sixth perforating device 35. As shown in FIG. 1 , the dispensing devices 20-25 are in a stored position, wherein the fluid agents 50-55 are maintained in a separated condition.

The multi-mix infusion bag 10 may further include a dispensing bar 16, wherein the dispensing bar 16 couples the dispensing devices 20-25 together such that the dispensing bar 16 may be moved in a direction toward the lower portion 13 of the bag 10. Moving the dispensing bar 16 in the direction toward the lower portion 13 results in simultaneously activating each dispensing device 20-25 and moving each into a dispensing position. Accordingly, it should be understood that in some embodiments each dispensing device 20-25 may be activated independently, and in other embodiments, the dispensing devices 20-25 may be activated simultaneously.

Referring again to the drawings, FIG. 2 depicts the multi-mix infusion bag 10 in a mixing condition according to embodiments. The dispensing devices 20-25 are shown in the dispensing position. When in the dispensing position, the dispensing devices 20-25 are each depressed toward the lower portion 13 of the bag 10.

In the order to dispense the fluid agents 50-55 into the lower portion 13 of the bag 10, plungers of each of the dispensing devices 20-25 are depressed toward the lower portion 13 of the bag 10 so that the point 92 of the needles 30-35 pierce the separating wall 18. The plungers may be depressed individually or may be depressed by applying pressure to the dispensing bar 16 which simultaneously forces all of the plungers into a depressed position. When depressed, the needles 30-35 have each pierced the separating wall 18. The needles 30-35 may each be a conduit, wherein the fluid agents 50-55 flow through the needles 30-35 respectively and enter into the lower chamber 12. When within the lower chamber 12, the fluid agents 50-55 are mixed together to form a mixed fluid 70 ready to be dispensed through outlet 60. Outlet 60 is configured to couple to known tubing for intravenously dispensing the mixed fluid 70 to a patient. During operation, it may be necessary to mix additional additives into the mixed fluid 70. Inlet 62 operates to allow the additional additives to enter the lower chamber 12 and be mixed with the mixed fluid 70. Further, hanger 64 may operate to operatively couple the bag 10 to a hanging device typically used to elevate infusion bags. In some embodiments, the lower chamber may be a size to hold at least the combined amount of fluid of the upper chambers.

As can be seen in FIGS. 4A-4B, dispensing devices 20-25 may include a plunger which may be the top portion of the dispensing devices 20-25. The plunger allows the dispensing devices 20-25 to be forced into a depressed or engaged location wherein the dispensing devices 20-25 are activated, allowing the fluid agents 50-55 to flow into the lower chamber 12 of the bag 10.

Additionally, dispensing devices 20-25 may include lip portion 90, wherein the lip portion 90 of each dispensing device 20-25 may engaged projections of a tube engagement with each upper chamber 40-45. The lip 90 inhibits removal of dispensing devices 20-25 once they are engaged within the tubes of the chambers 40-45.

Additionally, perforating devices 30-35 have various embodiments that are contemplated, such as, but not limited to a needle, a conduit and the like. For example each perforating device 30-35 may include a point 92 for puncturing the separation wall 18. Each perforating device 30-35 may also include a channel 94 wherein once the perforating device 30-35 punctures the separation wall 18. Channel 94 creates a fluid channel between upper chambers 40-45 and lower chamber 12. Fluid can then flow by gravity from the upper chambers 40-45 to the lower chamber 12. Other embodiments of needles 30-35 include a point 92 and a conduit perforating device having perforations 96 to allow fluid to enter the conduit portion and flow through an opening at the point 92. Fluid can them flow by gravity from the upper chambers 40-45 to the lower chamber 12. It will be understood that other types of needles may be used so long as a fluid communication between each of the upper chambers 40-45 and the lower chamber 12 is formed.

Referring to FIG. 5A another embodiment of a multi-mix infusion bag 110 in a stored condition, according to embodiments. The multi-mix infusion bag 110 comprises an upper portion 111 and a lower portion 113. The lower portion 113 comprises a main chamber 112. The upper portion 111 may comprise multiple compartments. For example, as shown, and without limitation, the upper portion 111 may include a first chamber 140, a second chamber 141, a third chamber 142, a fourth chamber 143, a fifth chamber 144 and a sixth chamber 145. The multi-mix infusion bag 110 comprises chamber separating members 117, to separate fluid agents 150, 151, 152, 153, 154 and 155, wherein first fluid agent 150 is held within first chamber 140, second fluid agent 151 is held within second chamber 141, third fluid agent 152 is held within third chamber 142, fourth fluid agent 153 is held within fourth chamber 143, fifth fluid agent 154 is held within fifth chamber 144, and sixth fluid agent 155 is held within sixth chamber 145. Additionally, the multi-mix infusion bag 110 may comprise a separating wall 118. The separating wall 118 separates the upper portion 111 from the lower portion 113 of the bag 110. The separating wall 118 serves to maintain the fluid agents 150-155 from entering lower chamber 112. The maintaining of the fluid agents 150-155 separate keeps the agents from reacting with one another until the appropriate time for the agents to be mixed. This increases shelf life. The first through sixth chambers 140-145 may each hold a predetermined amount of fluid. The separation of the fluid agents 150-155 constitutes the stored condition.

FIG. 5B depicts the multi-mix infusion bag 110 in a mixing condition according to embodiments. The upper chambers 140-145 are shown in a dispensing position, wherein pressure is applied to each upper chamber 140-145 to form a perforation in separating wall 118. When in the dispensing position, the perforations in the separating wall 118 allow for the fluid agents 150-155 to flow through the perforations and enter into the lower chamber 112. When within the lower chamber 112, the fluid agents 150-155 are mixed together to form a mixed fluid 170 ready to be dispensed through outlet 160. Outlet 160 is configured to couple to known tubing for intravenously dispensing the mixed fluid 170 to a patient. During operation, it may be necessary to mix additional additives into the mixed fluid 170. Inlet 162 operates to allow the additional additives to enter the lower chamber 112 and be mixed with the mixed fluid 170. Further, hanger 164 may operate to operatively couple the bag 110 to a hanging device typically used to elevate infusion bags. In some embodiments, the lower chamber 112 may be a size to hold at least the combined amount of fluid of the upper chambers 140-145.
